Research suggests that contemporary Americans are growing more and more accepting of premarital sex. As social mores around sex become more relaxed, people view premarital sex as part of the dating process. Even the most conservative, while not in full agreement, have become accustomed to the notion that sex occurs before marriage for the majority of the population.
Although chastity belts may have loosened, most will agree that extramarital affairs are a no-no. With widespread media attention on the extramarital affairs of celebrities, athletes and political figures, society shakes a condescending finger at infidelity. Also, unknown to many are laws in some states that not only view infidelity as illegal, but can make an unfaithful partner and/or third party liable for damages.
What may be most shocking is how the two relate. Some research associates the rise in marital infidelity to the widespread practice of premarital sex. Researchers purport that numerous relationships and sexual partners before marriage can relate to an individuals' propensity to be unfaithful once married. Having many partners before marriage makes monogamy difficult as we have become used to being with more than one person.
